Step-by-step explanation:
The area of a circle is given by :
A = πr²
r is the radius of the circle
(4) Diameter = 22 cm
Since, radius = diameter/2
r = 11 cm
Now, area of the circle,
(5) Diameter = 30 cm
Since, radius = diameter/2
r = 15 cm
Now, area of the circle,
(6) Diameter = 4cm
Since, radius = diameter/2
r = 2 cm
Now, area of the circle,
So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.

Answer:
400 students
Step-by-step explanation:
So 15 percent is 60 students
make an equation
0.15x=60
X stands for the total amount fo students and multiply that 0.15 becuase we know ti equals 60 and finding X will solve both problems
that’ll give you 400 students
if you check
400*0.15=60
So its correct

Answer:
<h3>60°</h3>
Step-by-step explanation:
Given that:
- Circumference (C) = 6 units
- Arc length (A) = 1 unit
<u>Find the central angle (</u><u>θ</u><u>)</u>
Arc is some part of circumference; thus,
the equation of arc length =
A = θ/360 × C
θ/360 = A/C
θ = (360×A)/C
θ = (360×1)/6
θ = 360 ÷ 6
<h3>θ = 60° ✅</h3>
Central angle = 60°
